I would also go so far as to argue that if these other language do in fact provide such a feature to flatten a list in the very simple way described, that is one of the most compelling arguments in support of adding that simple ability to Python. Nameerror Name Reshape Is Not Defined With Code Examples A name can be either related to a built-in function or to something you define in your program (e.g. We will go through the creation of a program that prints the Fibonacci sequence and while doing that we will see 4 different ways in which the Python NameError can appear.
